These systems are changing fast, especially in low- and middle-income countries. How can we be sure this transformation provides people with healthy and sustain

a caso. Isso permitirá que os países implementem políticas e práticas de biossegurança e biosseguridade laboratoriais economicamente viáveis e sustentáveis que sejam relevantes para suas circunstâncias e prioridades individuais.A necessidade de atualizar as diretrizes de biossegurança de laboratórios internacionais faz parte de uma iniciativa mais ampla para globalizar a biossegurança e enfatizar os princípios e as abordagens que são acessíveis a países que tenham ampla gama de recursos financeiros, técnicos e regulatórios. A OMS revisou o Regulamento Sanitário Internacional em 2005 “para ajudar a comunidade internacional a prevenir e a responder aos riscos agudos de saúde pública que tenham o potencial de cruzar fronteiras e ameaçar pessoas em todo o mundo”. Esses regulamentos exigem que todos os 196 estados-membros da OMS estejam bem preparados para surtos em potencial e novas doenças; isso inclui o diagnóstico precoce e a confirmação laboratorial para facilitar a prevenção e o controle de infecções.

Leishmaniasis is a vector-borne disease that is transmitted by sandflies and caused by obligate intracellular protozoa of the genus Leishmania. Human infection is caused by about 21 of 30 species that infect mammals. These include the L. donovani complex with 3 species (L. donovani, L. infantum, and
...
L. chagasi); the L. mexicana complex with 3 main species (L. mexicana, L. amazonensis, and L. venezuelensis); L. tropica; L. major; L. aethiopica; and the subgenus Viannia with 4 main species (L. (V.) braziliensis, L. (V.) guyanensis, L. (V.) panamensis, and L. (V.) peruviana). The different species are morphologically indistinguishable, but they can be differentiated by isoenzyme analysis, molecular methods, or monoclonal antibodies.

Important Update - Changes to WHOs Prequalification of IVD Assessment Procedure (from 2026)
Starting in 2026, WHO will introduce a new prequalification assessment procedure. The performance evaluation will no longer be part of the prequalification assessment and will become a separate procedure.

apid advances in development of medical devices are generating challenges in quality assurance for manufacturers and regulators, and in both quality assurance and product selection for procurers. Launched in 2010, WHO prequalification of in vitro diagnostics provides a valuable service to each of these groups.
